One of the first attempts to analyze the influence of the implementation way to introduce the ultrasonic field in
the electrochemical system was reported by E. Namgoong et al [89], analyzing the alternative approach to apply
ultrasound directly to the cathode, rather than the electrolyte solution itself, during electroplating experiments. In
this way, the idea of a specific design of a sonoelectrochemical reactor has been previously reported in the literature
by Reisse el at [90] and different approaches have been reported [91-93]. The necessity for the bipotentiostatic
control in some experiments [94] has been pointed out.
